Default Packages for Python

[simon-mo]

We should install some bare minimum packages such that model that depens on scimitar-learn can be deployed out of the box. I suggest

• numpy
• scipy
• scikit-learn

@simon-Mo if we just did NumPy and SciPy then a bunch of other things like scikit-learn would become very simple - if NumPy and scipy are already installed then you just need to add scikit-learn to pkgs_to_install. This way we make things like scikit-learn easier to deploy while still keeping our containers lightweight.
